Abstract: Implementations of a battery pack with reduced magnetic field emission are provided. In some implementations, the battery pack may be configured to reduce and/or eliminate the magnetic field normally generated while electrical current is being drawn from one or more cylindrical-steel electrochemical cells (e.g., AA batteries) by a connected electrical device. In some implementations, each electrochemical cell of a battery pack may include a conductive sleeve comprised of four conductive strips that are separated from the electrochemical cell by a thin insulating layer of material. In this way, the conductive sleeve provides a return path for electrical current that minimizes the loop area between the electrochemical cell and the conductive sleeve thereof. In some implementations, the four conductive strips of a conductive sleeve may be equally spaced 90 degrees apart and/or positioned longitudinally on a cylindrical-steel electrochemical cell, separated therefrom by the insulating layer of material.

In one particular form, shutting down the stack upon detection of a leakage of fuel either within the stack or from the stack involves depressurizing and uniform consumption of hydrogen by catalytic consumption in the cathode of all cells.
